The 3rd generation of JW Fishers’ ROV, the SeaLion-3, is the most sophisticated submersible to date. The new, standard turnkey system offers the most sensors and payloads of any other ROV on the market at no additional cost. No more paying higher prices for the necessary tools needed to complete your mission.
This SeaLion-3 can dramatically reduce search time and the high costs associated with diver-based inspections. With the SeaLion-3, your team can locate, inspect, and videotape a target without entering the water. The SeaLion-3 can also narrow the search area so that when divers are required, their time is spent on the target instead of swimming grid patterns. When outfitted with a metal detector (JW Fishers RMD-1), the ROV can search for weapons, unexploded ordnance, pipelines, anchors, buried treasure, or other metallic objects. When an optional sector scanning sonar is added, the searching capabilities become endless and allow for searching in “zero visibility” conditions.

The ROV has a powerful and sophisticated seven (7) motor, vectored propulsion system with 2x as many thrusters for horizontal movement and is twice as powerful as its SeaLion-2 predecessor. The (4) four vectored thrusters allow horizontal motion in any direction and the ability to rotate in place. Vertical power is also increased, with (3) three thrusters for diving and lifting. The unique vertical thruster placement also provides the ability to adjust the pitch and trim of the ROV. An off-the-shelf Logitech USB controller (supplied) operates the system. A joystick controls the horizontal motors (forward/reverse and turning) – it can hover “in place” and rotate 360 degrees. The second joystick controls the vertical motors (up/down and lateral movement).
The SeaLion-3 Topside Control Unit (TCU) includes a 15.6″ TFT Active-Matrix LCD Panel (video monitor) with a 1920 x 1080 Full HD content display for viewing live camera feeds and reviewing media files (video and images). The secondary Control Monitor is a 12.1″ TFT Active-Matrix LCD touchscreen for controlling the ROV system.
The SeaLion-3’s dashboard screen is a comprehensive tool that gives users a complete overview of the ROV’s operation. It provides detailed power information, ROV heading, and component status, ensuring the user is always informed and in control of the SeaLion-3 operation.
